J.J. Putz has allowed opponents to hit .529 off him in five appearances since coming off the disabled list two weeks ago and today the Diamondbacks decided they’ve seen enough, designating the veteran reliever for assignment.

Prior to struggling this season Putz posted a sub-3.00 ERA in four consecutive years and saved 32 games for the Diamondbacks as recently as 2011. He’s also being paid $7 million this season, but Putz has always struggled to stay healthy and at 37 years old the last-place Diamondbacks obviously don’t see the upside in giving him a chance to get back on track.

None of the other 29 teams are going to touch his contract on the waiver wire, but it’s possible the Diamondbacks could find a taker via trade if they eat nearly all of his remaining salary. And if not Putz should be able to latch on somewhere as a middle reliever once Arizona releases him.
